TILE.

To-all whom itv may concern:

Be it known that I. JOSEPH W. FARB, a citizen of the United States, residin at Chicago, in the 'county of Cook and tateof l Illinois, have invent-ed a new and useful Tile,

of which the following is a specification.

My invention relates to improvements in tiles in which a frame is provided which is adapted to` fulfil the strnctural requirements of a tile as far as' strength and assembly are concerned and which ,will also support and carry the tile-element; and thel objects of my improvement are, iirst,' to reduce the weight of the tile which, at present, has to b e specially provided for in the structure to which they are applied, second, to facilitate the application or assembl greatly strengthen `t e tile, and, fourth,. to

along the line X-X of Fig. 1, and Fig.v 4 is an end view of two tiles in assembly.v

Similar Vletters refer to similar parts'V throughout the several views.

The supporting frame comprises a plurality of parallel, properly s aced ribs, a, held in proper relat1on to eac a,by nailing or riveting or in any other 'suitable manner. The ribs, a, however, should be disposed to4 pro'ect away from the crosse strips and theres ould be no mortising to bring the ribs andcross-strips into the same planes. Around the ribs, at proper places, are dis osed the wire loops,c, whichv are adapte to be twisted around the rafters or other su port to which the tile is tobe finally attache to hold it firmly in place. V means mayv beattached to the ribs for this purpose withoutdeparting from the spirit of my Invention. 'I have found, however,'that wire loops, such as here described7 ada t themselves to be readily adjusted and will secure the tile in place in a' most permanent way and, at the same time, permit a'tle to be removed and another put in its place with lace. l

ing frame and cemented to the upper surface i of the crosspieces and around the ribs I provide a textile fabric; either metal or ber', or a pliable piece' of 'what is known in the market as ex anded metal. vThis layer or eleletter d.

U on the up er surface of the fabric o r expan ed metal spread a thin layer, e, of suit- .able cement composition which enters somewhat into the `fabricor expanded metal and inf.' a thin cement tile coating for the frame. t will be seen that the 'ribs produce ridges tile.` This I consider an important element in the structure. The corrugations in the cement layer; and, the corrugations extendcement of which the corrugations are made inforcing bars because in that case the ce ment is still the real structural element.y It has the Weight, cost, brittleness and expansion and contraction ofthe ordinary tile and acquires merely ya greater resistance in cer= tain directions. It is quite impracticable to mold cement in sheets as thin as the layer I much less the structural qualities necessary in commercial tile. i The cement layer 1n my tile being so thin itself peculiarly to the service required 'o f covering tile. In ordinary tile provision has to be made for expansion and contraction; but with `my tile the thin somewhat .elastic cement 4covering bends' in its corrugations and nov suchl provision has to. be made.

As is well known tile is never worn away to any appreciable extent. The surfaceof the tilev isrits principal feature and the vmuch greatenbulk and wei ht of material behind the surface being ad ed merely for strength and Istructural and assembly purposes..

It is'A possible to make my tile in pieces having a much greaterv covering surface than cement coating in themselves strengthen thcV vment .is esignatedin the drawings by the when it hardens firmly adheres thereto makl Or-cOrrugations in the surface of the cement"V ling partially around the ribs' as they do, the' more firmly fixes the ribs in place while the The thin layer of cementy ture formed by melding cement around reemploy and have them retain'their shape4 has considerable more elasticity and'adapts ordinary tile on account of its lightness and strength. In order to overcome 4the prejudice that usually encounters the introduction of a new article-to the market, I have given the surface the appearance of several of the usual tile as they Aare ordinarily laid, with the exception that each tile appears to have a corrugated side.

As clearly shown in the drawings, the side, A, is provided with a channel, f, upon its under edge which is of suiiioient heightI to receive the side, B, of the next adjacent tile provided, as is seen, with the ridge, g. This ridge, g, upon the side, B, is to prevent moisture from seeping into and trickling through the joint.` The end, C, of the tile is also provided with a channel similar to the channel, f, which is adapted to overlap the end, D, of the next adjacent tile. It will be further seen that I extend` the fabric or expanded metal layer, d, beyond the cement layer, e, on the side B, and end, C, of the tile. After the tile has beenpr'operly secured in placel this extended portion of the fabric is cemented to the adjacent tile to completely seal the joint. The ribs, a, do not come quite to the end, C, of the tile while they project a short distance beyond the end, D. This is to secure a dovetailing or mortising of the respective tile together byl means of the overlapping -of the cement and underlapping, so to speak, of the ribs. Again it will be noticed that the cross-strips, b, project from both sides of the tile and are disposed at an angle with the ribs so that the ends of the cross-strips upon adjacent tile cannot abut. This arrangement is for the same over and under lapping-purpose.

I will now outline the best method, as far as I know, of constructing my tile.

Inorder to give the outer surface of the tile a suitable appearance, I employ a mold (not shown in the drawings) having suitable depressions running entirely across it for 'forming the corrugations and any other superficial configuration which it may be desired to give to the surface of the tile. I cover this mold or form with a suitable cement` layer, e, in a very plastic condition to only a slight depth. While this layer of cement is still in a .plastic condition, I place upon it either the textile or expanded metal, d, so that the cement in hardening will harden in and about said textile or expanded metal and firmy adhere thereto.v In the mean time I have had prepared the frame Work comprising the pieces, a, which are of such'size and length to fill the corrugations in the cement and fabric layers, and the cross-strips, bi There are a sufficient number of the pieces, a, to iill each corrugation, and they have been properly spaced to corre, spond with the corrugations. After the frame has'been so iixcd I provide the pieces, a, at suitable intervals with the wire loops, c.

Before the cement and fabric layers have hardened, I place upon them the frame so that the pieces, a, will rest in the corruga tions. I then -lill in the corrngations with suflicient cement to secure an adhering between the 'frame and the fabric and cement layers and permit thewhole to harden.

Having now described my improved tiie and. a suitable method of producing same, what I claimas new and desire to secure by Letters Patent is 1. A tile comprising a frame work of parallelly disposed projecting ribs and transversely disposed cross-pieces, a reticulated layer having corrugations into which proj ect said projecting ribs, and an hydraulic cement filling and coating for .saidv reticulated layer.

2. A tile comprising a frame work of parallelly disposed projecting ribs and transversely disposed cross-pieces, pliable loops surroundingI and. extending rearwardly from said ribs, a reticulated layer cemented to the side of said frame from which said ribs pro ject having corrugationsfor thc reception of said projecting ribs, and an hydraulic ce ment 'filling and coating for said inticulatcd layer.

3. A tile comprising a frame work having an uneven supeiiicial mm'l'iguration, a reticn lated covering for said frann work adapted to coliform to the uneven contigui-ation thereof, and an hydraulic coment coating for said coveringl of sulicicnt thinness at the uneven portions thereof to permit of bending to accomn'imlate the natural expansion and contraction of the cement.

4. A tile comprising a frame work having projecting ribs, a rcticulated covering for said framework corrugated to accommodate said projecting ribs and an hydraulic, cement *filling` and coating l'or said covering of suliicient thinness to permit of bending to accommodate the natural expansion and contraction of the cement.

A tile comprising a frame work, a rcticulated covering for said frame work and an hydraulic cement iilling and coating `for said covering of sullicient thinness to permit of its bending to accommodate the natural expansion and contraction of the cement.

6.` A tile comprising a frame work of uneven superiicial conliguration, a lreticulated covering extending beyond said frame work upon two sides and adapted to conform to the uneven coniilruration thereof, and an hydraulic cement filling and coating disposed upon that portion of said covering which is above said frame work.

In testimony whereof I have hereunto set my hand in the presence of two witnesses. JOSEPH W. FAHR. Witnesses:
